EDWARD S. GEROW, OF CORDELIA, OALIFOREIA.

' WAGON-JACK.

SPECIFICATION forming part of Letters Patent No. 236,154, dated January4, 1881,

' Application filed October 18,1880. (No model.)

To all whom it may concern:

Be it known that I, EDWARD S. GEEow, of Cordelia, in the county ofSolano and State of California, have invented certain new and usefulImprovements in Wagon-Jacks; and I do hereby declare that the followingis a full, clear, and exact description of the invention, which willenable others skilled in the art to which it appertains to make and usethe same, reference being bad to the accompanying drawings, which form apart of this specification.

Figure 1 is a perspective view, and Fig. 2 is a vertical sectional view.

Oorrespondin g parts in both figures are denoted by like letters ofreference.

This invention relates to wagon -jacks or lifting-jacks; and it consistsin certain improvements in the construction of the same, which will behereinafter more fully shown and specified.

In the drawings hereto annexed, A represents an upright or standardprovided with two lateral arms, 13 0, provided at their outer ends withopenings D for a vertically-sliding stem, E, provided at its upper endwith a button. F.

The upper end of standard A is provided with a transverse slot, G, inwhich is pivoted a lever, H, the short arm of which, I, is connected bya twisted link, J, which passes through an opening, 2, of bracket B, andconnected with a plate, K, having a perforation or open ing, L, for thestandard orvsliding stem E, which passes through the said opening L, aswell as through the openings D in the arms B C of upright'A.

The lower rear end of the upright A is provided with a hook, M, by whichthe long arm or handle of the lever H may be secured or retained in alowered position, so as to maintain the stem E in a raised position whenso adjusted.

From the foregoing description, takenin connection with the drawingshereto annexed, the operation and advantages of my invention will bereadily understood.

After placing the wagon-jack in position, with the button F of stem Eunder the axle of the vehicle, the said stem-being raised so as topermit such adjustment, the long arm of lever H is lowered, thus raisingthe link J and plate K, and with the latter the stem E, which is heldthereto by frictional resistance. It will thus be seen that the end ofthe vehicle-axle may be raised or lifted to any height required for allpractical purposes. To lower the stem E the lever H is released from thehook M and elevated, which causes the inner surface of the twisted linkJ to abut against the standard A, thereb; raising the plate K, whichaction permits the stem E to slide by gravity through said plate. 1

The stem E, which may be made of any desired length, enables my improvedjack to be applied to wagons of almost any size and height.

I am aware of the Patent No. 200,117, of February 5, 1878, and I do notclaim the construction therein shown.

Having thus described my invention, I claim and desire to secure byLetters Patent of the United States- In a lifting or wagon jack, thecombination of the transversely-slotted standard A G, having perforatedbrackets B O, the lever H, pivoted in the slot of the standard, andhaving the twisted link J, passing through opening a of bracket B andconnected to the perforated plate K, the vertical stem E, sliding intheopenings D D L of the brackets and plate, and the hook M, the wholeconstructed and arranged to operate as shown and described.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in presence of two witnesses.

EDWARD SEARLES GEROW.
